Claims.

The invention relates to a metal barreljand involves an improvement in'double walled barrels or other similar containers wherein an inner sheet metal casing is spaced from an outer sheet metal casing and supported therefromin such a manner as to aflord the maximum degree of protection to the inner casing from impacts upon theouter shell when the barrel is in use, and in such a manner as to afford a high degree oi thermal insulation for the contents of the barrel by means of the structure'and arrangement of the parts thereof.

One of the primary objects of the invention, therefore, is the provision in a sheet metal barrel i'of a double walled structure wherein an inner casingis spaced from an outer casing by a minimum of supporting means in order to minimize the damage to the inner shell by impacts upon the outer 'shell when the barrel is in use. It is i also an object of the invention to provide a double walled sheet metal'barrel which is so constructed that blows received upon the outer casing are not transmitted to the-inner casing in such a manj ner as to indent or deiorm the inner casing to i such anextent as to as:'-:ct the volume thereof or otherwlse damage the inner casing. A further object of the: invention s the provision of improved means for supporting the inner casing from the outer casing of a double walled sheet metal barrel. A still further object of the invention is the provision of improved means for reinforcing the chime portion of the barrel. A still further object of the invention is the provision of improved means for reinforcing the bilge-oi i the outer casing.- Itis also an object of the invention to provide means upon the exterior of the Fig. 2 is a plan view, partly in section, of the barrel shown in Fig. 1 and showing the improved seal attaching means in position thereon;

Fig. 3 is a transverse sectional viewtaken on the line 33 of Fig. 1; Fig. 4 is an elevational view of the chime ring 5 assembled on the outer head and the inner casing;

Figs. 10 and 11 are detailed views showing the means by which the seal is secured in position over the tap opening; and

Fig. 12 is a vertical sectional view showing the utilization of separate tap and vent openings, and

a slightly modifiediorm of inner casing.

As disclosed herein my improved barrel comprises an outer sheet metal casing, lwhich is preferably formed from two substantially semi-cylim drical sections 2 and 3 pressed from rectangular sheets and provided with a circumferential bilge.

In assembling the barrel the longitudinal edges i and 5 of the sections 2 and 3 are welded together, preferably by a butt welding operation, and these edges have locating plates 6 welded to the inner face thereof, alternating plates being secured to one section only in order that the edges of the sections may be properly alined in the assembly thereof.

Each of the semi-cylindrical sections 2 and 3 is pressed outwardly to provide a circumferential bilge reinforcing rib i, and this rib is preferably provided with a continuous series of flattened portions 3 in order to retain the barrel in a. position of rest when supported upon the bilge. I The opposite ends of the semi-cylindrical sections 2 and i are provided with outwardly pressed rein- "forcing head ribs 9, and outwardly pressed intermediate rios iii are provided between each of the head ribs ii and the bilge rib I. The intermediate ribs it we likewise provided with a continuous series flattened portions ii for engagement with operating rolls, of a washing machine so t at rotation of the barrel may be insured as it moved through the machine. The free edges of the head ribs 9 are turned inwardly to proride annular flanges l2 to which the margins of the outer heads 13 are secured.

The two outer heads I! are similar in construction and are preferably pressed from a. circular sheet of metal so as to'form a dished structure with a substantially flat bottom ll having an upright rim l5 flaring outwardly at l6 and provided with a marginal portion I! which is welded to the inner face of the annular flange II on the free edge of the curved wall of the outer casing I. As shown in Fig. 2, one of the outer heads H, or both if desired, may be provided with arcuate depressions l8 in which the name of the owner may be embossed, and which also serve as strengthening means for the outer heads.

The rim it of the dished outer head therefore provides a chime flange which is substantially spaced from the curved side wall of the outer casing so as to form an annular channel l9 as clearly shown in Figs. 1, 6 and 12. The chime thus provided is reinforced by means of a chime ring 20 which serves the purpose of a combined chime reinforcing member and inner casing support. For convenience in manufacture, the chime ring 20 shown herein is formed from four similar arcuate members with the meeting ends thereof welded together to form an integral, rigid structure. It will be understood, however, that this ring may be pressed from a single blank if desired, or it may be formed from any desired number of separate parts, and it will also be understood that it is not essential, where the ring is made up of separate sections, that the ends of the sections be welded or otherwise secured together.

As I have disclosed the same herein, the chime ring 20 is substantially S-shaped in cross section. The end of the outer loop is welded to the marginal portion ll of the outer head l3, and this loop extends inwardly for some distance in con tact with the inner surface of the head rib, as shown at 2i, thence extends transversely across the annular channel at 22 and inwardly at 22 in engagement with the chime flange to which the lower loop is welded. The lower loop is then inclined outwardly as at 24 across the space between the outer head if and the end wall 25 of the inner casing 25 and is then curved to form wise the portion 2l-of the inner loop between the outer head I: and the end wall 25 of the inner casing 26 is provided with a circumferential series of perforations ll in order to decrease the weight and reduce the thermal conductivity thereof, and in order that the space between the side walls of the casings l and 26 may be in communication with the space between the adjacent end walls II and 25 of the casings.

The inner casing 20 is preferably formed from two substantially similar tub-shaped sections 32' and I! pressed from sheet metal so as to provide an outer circumferentially curved wall 34 which is preferably slightly curved in a longitudinal direction and meets the end wall 25 along the rounded edge 28 heretofore referred to, as shown in Figs. 1, 6 and 12. The free edges of the inner casing sections are turned outwardly to provide annular flanges 35 which are welded together in the assembly of the barrel. As hereinbefore indicated, the rounded edges 28 between the side wall 34 and each of the end walls 25 of the inner casing are supported within the seat 21' formed by the curved inner edge of the chime ring 2'.

With the construction above described, it will be noted that the inner casing 2i is spaced throughout its extent from the outer casing I, and is supported from the outer casing solely by the engagement of the chime ring 20 about the ill edges thereof. Inasmuch as the space between the casings contains only air, impacts or blows received by the outer casing are not transmitted to the inner casing and therefore do not deform the inner casing, and, as will be apparent from the drawings, either the side or end walls of the outer casing may be indented to a considerable extent without any deformation or other injury to the inner casing. In case of a severe blow upon the chime of the barrel, the structure which I of the inner casing, a pad or cushion 38 of asbestos or other insulating material is secured centrally between each inner head 25 and the adjacent outer head l3. This pad may be held in, place by a metal clip 36' welded to the outer head it and having its opposite ends bent transversely so as to embed themselves within the pad as shown at 31 in Fig. 12.

in order to protect the barrel against damage from the severe blows which are ordinarily received upon the bilge portion, I prefer to reinforce 85 this portion by means of a bilge reinforcing ring 38 extending circumferentially within the bilge rib 1 and welded therein. The reinforcing ring 38 is preferably made to conform to the flattened portions 8 of the bilge rib, and is of such a width 40 as to extend transversely across the rib, the edges thereof being turned inwardly as shown at 20 and .thence outwardly as at MI in order "to provide additional strength. The reinforcing ring 32 may also be provided with a circumferential series of relatively large perforations 4] in order to reduce its weight. As shown herein, the ring 28 is formed 7 from two semi-circular sections with the meeting ends thereof welded together and is so positioned that the joints therein coincide with the longltudlo nal meeting edges 4 and I of the outer casing sections. It will be understood, however, that the ring 32 may be integral or it may be formed from I more than two sections if desired.

In the form of my invention disclosed in Fig.

1, I provide a. bung opening comprising a bung bushing 42 secured in alined openings in the inner casing, the-bilge rib and the bilge reinforcing ring, the openings in the bilge-rib and the bilge reinforcing ring preferably being located centrally of one of the flattened portions 8. The inner and outer faces of the bushing 42 are preferably flat and the area immediately surrounding the opening in the inner casing is preferably flattened as shown at 42 to conform thereto, and 5 the inner and outer faces of the bushing are suitably welded to the inner casing, the bilge relnforcing ring and the outer casing. In order that proper drainage of the barrel may be effected during the washing operation, I prefer to provide the inner face of the bushing 42 with oppositely arranged slots 44 inclined inwardly, with the wall of the inner casing pressed outwardly Ego the slots and conforming thereto, as shown in aioasao The inner end of the opening through the bushing 42 is provided with a circumferential flange 45 to serve as a stop for the bung 44 and to prevent the same from being forced into the interior of the barrel. In order to provide against the accidental removal of the bung 48, I preferably'provide the outer end-of the opening through the bushing 42 with a circumferential groove 41 for receiving a split ring 48 or other form of retaining means, such as a dished plate, when the bung is in position.

A tap opening is provided in the upperhead of the barrel in the form of a tap retainer 49 secured between the outer and inner heads in alined openings therein, Preferably the opening in the inner head 25 is provided with an inturned flange ii the free edge of which is welded to the retainer 49 as shown. The retainer 49 is also provided with an outwardly projectingflange 52 resting upon the outer face of the inner head.

25 and welded thereto. It will also be understood that the outer end of the retainer 49 is suitably I welded to the 'outer head 13. The opening through the retainer-49 is preferably threaded to receive a threaded tap bushing 53 such as shown in Fig. For in Fig. 8. In the form shown in Fig. 7 the tapered opening inthe bushing 53 is provided with inwardly projecting lugs 54 for engagement with a tap connection, and these lugs,

may also serve as stop means for a wooden plug 55 of well-known construction. Inv the form shown in Fig.- 8 the tap retainer 49 is similar to that shown in Fig. 7, but the bushing 86 is provided with a straight opening closed by means of a plug 51 which may be driven therethrough when the tap connection to the barrel is made.

For the purpose of securely aiiixing a stamp 58 or other seal to the barrel I have devised improved means wherein a pair of cars 59 is provided on opposite sides of the tap opening, and a strip of metal 60 is extended across the tap over the stamp 58 and has its ends secured to the ears. Preferably, the ears 59 are-welded or otherwise secured within recesses 6| formed in the outer head on opposite sides of the tap opening, and they are of such a height with respect to the recesses 6| that the lower faces .of the ears I are slightly below the outer surfce of the head. as

shown in Figs. 9, 10a'nd 11. The inner edges of the ears are positioned near the abrupt inner walls 62 of the recesses so that the sealing strip '64 binds upon the upperedges of the walls 82 and is held in place thereby. Such 'a structure is effective in preventing the accidental removal of the'seal and may also be utilized for preventing the accidental removal of the plugs 54 and 51.

In the modification of my invention shown in Fig. 12 the inner casing 26' is formed from two similarend sections 63 and 64 and an intermediate circumferential section 55, the meeting edges of each of the end sections and the intermediate section being provided with outwardly turned flanges 68 which are welded together when the sections are assembled. The end sections 63 and "are formed ina manner similar to the two sections 32 and. 33 of the inner casing 26- hereto- 1 I fore described. The outer casing I, comprising the longitudinal sections 2' and 3' and the heads i3, is similar in construction to the outer casing l. The construction of the chime ring II and its arrangement with respect to the other elements do not differ from the construction and arrangement of the chimering 20. Further description of these features is therefore omitted.

outer casings as'shown at II and" in order to provide suitable flat surfaces for engagement with the opposite faces of the retainer 61, and the bottom wall of the inner casing may be depressed as shown at H in order to insure proper drainage of the contents from the tap opening.

It will be understood. that the barrel, con

structed as above described, may have its outer surface finished or coated in such manner as may bedesired. and that the interior of the inner casing may be coated to accord with the liquid contained therein. Irrespective of the character of the inner coating, nay-improvement provides a structure in which there is little likelihood of this coating being damaged by reason of blows received by the outer casing. The manner in which the inner casing is spaced from the outer one and supported therefrom provides efficient and economical thermal insulation for the contents of the barrel, and I regard this as one of the important features of my improvement.

Although I have shown and described certain forms which my invention may take, it will be made therein, without departing from the invention, so long as such' changes come within the scope of .the appended claims.
